What is an eSIM?
eSIM stands for “embedded” SIM which is installed in your phone by scanning a QR code or tapping a notification. If an activation date is required the QR code / Notification is sent after activation, else 24hours after completing your documentation.
eSIM Advantages
- Easy to use: Set up your plan by scanning a simple QR code or tapping a notification.
- Save on Shipping cost: No physical delivery requirement
- Save on time: In a rush to travel? We will send eSIM QR Code via email. Scan it as per instructions and It will be ready to use upon arrival.
- Keep your original SIM: The eSIM is in addition to your original SIM which will work as usual if you need it.
eSIM Disadvantages
- Unfamiliar: Since it is a new technology expect to be learning a bit.
- eSIM Compatible Phones: eSIM will only work in eSIM compatible phones. As a general rule, iPhone 11 and Android model 2021 and higher models are compatible with eSIM.
- Single Use Only: Most eSIM codes can be used only once. Please do not delete the eSIM created on your phone, since it cannot be recreated on your phone or any other phone. However you can de-activate the eSIM when not needed from your settings.
- Transfer of eSIM: To transfer an eSIM from one phone to another you must visit the store of the Operator concerned. However some USA eSIMs can be transferred from one iPhone to another.
Activating eSIM on your Device using a QR Code
Most eSIMs are installed using a QR code. The QR code is sent to you by eMail. You need an Internet connection to install an eSIM
iPhone XR, XS and newer
- Go to Settings, then Cellular.
- Select Add a plan, and the Camera app will open.
- Point your camera at the QR activation code until you see a message that says Installing cellular plan.
2021 Android and newer
- Go to Settings > Connections > SIM card manager
- Tap Add mobile plan
- Tap Add using QR code
- Scan the QR activation code
Activating eSIM on your Device using an Operator Notification
T-mobile, AT&T and some other operators make it even simpler to install eSIMs. They send a notification directly to your phone. Just tap on the notification and follow the instructions as in images below. The notification is sent to the phone you intend to use on your trip for which you have given us the EID and IMEI number by dialing *#06#.

I purchased this sim on January 23rd for travel to Vietnam between Feb1st to Feb8th. I landed in Vietnam at Ho Chi Minh and tried connecting to the network as i wanted to use Grab from the airport to get to my hotel. While the sim showed me network availability – it didnt allow me to connect to the network. I tried endlessly for a couple of hours. I was also talking to the Tsim representatives during this time trying to get a resolution. Unfortunately the sim just refused to work. After a few hours wasted in trying to get it to work, the Tsim folks offered me a full refund since the sim was simply not working. I just got myself a local sim then which i used for the rest of my trip.
So based on my experience.
1. Tsim is reliable and at least tried to help me with the connectivity issue failing which they returned my money – which makes me trust them.
2. I would not recommend this particular sim as based on my experience it is unreliable.
3. Getting a local sim in Vietnam was easy and worked fine without a breeze. Just a side note, the price of the sim in Vietnam was only slightly cheaper than purchasing it online via Tsim. Kudos to you guys for being honest to your customers.

This is the second time I purchased a TSIM sim and my experience has been very good. The connectivity was very good in all the places of Vietnam that I visited. I would highly recommend this sim before travelling instead of depending on sims purchased locally. Thank you for the excellent service.

I guess it was a good idea to take a SIM from India, though we eventually bought local sims there for the rest of the folks who were traveling with us. We did use this mainly for data thru hotspot and it worked well across.
Most of the local sims are sold without asking for any documents in Vietnam and there is always a risk of getting locked out with no solution except for buying a new SIM. We bought this as additionally as a back up in such situation (which never arised)
